SKF Reliability Maintenance Institute phần 3 pot

Recommended for

Engineers managers and technicians whose responsibi￾lities require them to be proficient in the setup and use

of Vibration Control and Protection systems; mainte￾nance supervisors, Plant Managers, Reliability engi￾neers, Instrument & Control Engineers interested in

vibration protection and control.

Course Objective

The course objective is to provide a theoretical and

practical approach to understanding the theory and

functionality of vibration protection and turbine super￾visory systems that are widely used in industry.

Course Description

Designed for maximum of 12 class participants. A

combination of overhead presentations, group exercises

and case studies are used. Participants are encouraged

to bring along issues faced in the field. The knowledge

gained will enable the participant to improve turboma￾chinery reliability.
